我正在尝试自动更新我的位置，并在位置发生变化时让云相关代码的其他部分正常工作。这是我服务的代码：

将弹出“to inside detectLocation”之前的toast，并记录日志条目，直到
04-04 00:42:34.687: V/X(10217): Response:After lm1.requestLocationUpdates
但除此之外，代码无法访问...... 即使GPS标志显示在操作栏中，但显示位置的吐司也没有弹出...请帮助...... !!!
答案 0 :(得分：0)
在requestLocationUpdates(LocationManager.GPS_PROVIDER, 10, Two_Min, ll1)中，您将Two_Min（已设置为5 * 60 * 1000 = 300000）传递到minDistance参数，该参数应为数米。尝试将minDistance设置为0。
